tube pre amp plus solid state power amps?

HI there,
My systems have always been tube system all the way through phon stage + pre amp+ power amps, but recently I got a little tire of maintenance of these amps and thought about changing power amps to solid state. I listen classical music. I always love tube amp particular from my LP collection. I am worrying about using solid state power amp will loose the texture of the sound that I like. However, I have done a little reading, some one said high end power amps will keep that sound, especially something like McCormack DNA-500 and Claytons amps. There are some writing confuse me, such as: β€œit is not important to use tube phon stage, solid state will be better.” I even read the statement says: pre amp is the least important of the whole audio chain.”

Well, what I am thinking about is keep tube system for both my phon stage and pre amp, use solid state for power amps replace tube system. Does anyone can tell me this will be a good change, or I need either whole system on tubes or on solid state?

Thanks

I always used that combination in the past because I could not afford a high powered tube amp. Recently I purchased a tube amp, they are much better to my ears.
I also have a tube pre and high quality SS. The difference is in your depth of listning. If you are going to get serious, you got to go all tubes; although tube SS is very good.

thanks for all your input. I decided stay in tube for a while. however, I recently saw Pass Xono phono stage SS, wonder if will go well with my Carry 05 pre amp. I try to up date my phono stage, try to match Carry.
thanks

more question about impedance . my Carry out impedance is 400K and my Rogue in impedance is 200K. is that Power amp incoming impedance should be higher?

Suikang, The output impedance of the Cary SLP-05 preamp is only 400 ohms not 400K or 400,000 ohms. The input impedance of the Rogue M150 is indeed 200K ohms or 200,000 ohms, which is 500 times the ouput impedance of the SLP-05. Many say the ratio should be at least 10 and I like to see a ratio of at least 20 for input impedance to output impedance to avoid rolling off the low frequencies. The input impedance of your Rogue amps is about as high as it gets (a good thing) and the resulting ratio of 500 will work just fine.
